Embodiment Construction

[0032] see figure 2 , 3A , 3B, 3C, the present invention provides a molding die of thermoplastic composite material, comprising:

[0033] The lower mold 10 has a first forming surface 11, a first end surface 12 opposite to the first forming surface 11, a ring side surface 13 is arranged between the first forming surface 11 and the first end surface 12, and the first forming surface 11 A trough 14 is recessed on the top, and a positioning ring groove 15 is recessed on the first forming surface 11. The positioning ring groove 15 surrounds the trough 14. The lower mold 10 penetrates an air passage 16, and the air passage One end of 16 is located on the first forming surface 11 and between the trough 14 and the positioning ring groove 15, and the other end of the air channel 16 is located on the ring side 13;

[0034] In this embodiment, the lower mold 10 further has a plurality of first positioning through holes 17, the first positioning through holes 17 respectively pass thro...

Abstract

The invention discloses a thermoplastic composite material forming die and a use method thereof. The thermoplastic composite material forming mold mainly uses an upper die and a lower die, and througha first step, a second step, a third step and a fourth step, a thermoplastic material and a fiber woven fabric material are placed in a mold cavity of the die and the thermoplastic composite materialis quickly and easily formed, so that the processing steps of the thermoplastic composite material can have the advantages of fewer processing steps and short forming cycle.

Description

technical field [0001] The invention relates to composite materials, in particular to a molding die for thermoplastic composite materials and a method for using the same. Background technique [0002] Composite materials can be divided into fiber composites, sandwich composites, solid sandwiches, honeycomb sandwiches, fine-grained composites, hybrid composites, intralayer hybrids, interlayer hybrids, sandwich hybrids, and intralayer / interlayer hybrids according to their structural characteristics. , ultra-hybrid composite materials, etc., according to their different materials, there are two types of thermoplastic fiber composite materials and thermosetting composite materials. The molding cycle of thermoplastic fiber composite materials is much shorter than that of thermosetting composite materials. Therefore, it is widely used The thermoplastic fiber composite material is mainly made of fiber material and thermoplastic resin, so that the thermoplastic fiber composite mater...
